[jira] [Created] (ARROW-13617) [C++] Make Decimal representations consistent

David Li created ARROW-13617:
--------------------------------

             Summary: [C++] Make Decimal representations consistent
                 Key: ARROW-13617
                 URL: https://issues.apache.org/jira/browse/ARROW-13617
             Project: Apache Arrow
          Issue Type: Improvement
          Components: C++
            Reporter: David Li


Right now Decimal128 is represented as two 64-bit integers (in native endian order) and Decimal256 is represented as a std::array (in native endian order). We could make these consistent (presumably there should be no performance impact). It may also make it easier to extract a common base class or other niceties.
